Contests and Prize winnings

A charity golf outing advertised that any player making a hole-in-one on the 8th hole would win a new car. The tournament was 18 holes of golf. I made a hole-in-one on the 8th hole during the second round of play. The score was marked in the box numbered 17 on the scorecard. After, the tournament claimed that only a player making a hole-in-one on the 1st round would win a car. Should I be awarded the car, and if so, could I take it to court?
